inverse oflaplace (e^{-7s})/(s^2)

inverse laplace

\frac{e ^{- 7 s}}{s ^{2}}

H (t - 7) (t - 7)

Solution steps

L^{- 1} {\frac{e ^{- 7 s}}{s ^{2}}}

Apply inverse transform rule:

L^{- 1} {F (s)} = f (t)

then

L^{- 1} {e^{- a s} F (s)} = H (t - a) f (t - a)

Where

H (t)

is Heaviside step function

= H (t - 7) L^{- 1} {\frac{1}{s ^{2}}} (t - 7)

L^{- 1} {\frac{1}{s ^{2}}} : t

= H (t - 7) (t - 7)

\int 2 sin (x^{2}) d x

\int \frac{2 x - 3}{( x - 1 ) ^{3}} d x

\int 13 tan^{5} (x) sec^{4} (x) d x

x \to 5 - lim (\frac{x + 1}{x + 5})

\int 30 + cos (x) d x
